DEVICE FOR ORNAMEN TING THE TOPS 0F LAMP-CHIMNEYS, &c.

SPECIFICATION forming part of Letters Patent No. 440,494, dated November11, 1890.

Application filed March 10, 1890.

To all whom, it may concern:

Be it known that I, JOSEPH MCMUETRY, a citizen of the United States,residing at Pittsburg,in the county of Allegheny and State ofPennsylvania, have invented new and useful Improvements in Devices forOrnamenting the Tops of Lamp-Chimneys; and I do hereby declare thefollowing to be a full, clear, and exact description of said invention,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

My invention relates to new and usefulimprovements in devices or toolsfor beading the tops of lamp-chimneys.

The object of my invention is to provide a tool which will flare thetops of chimneys and place thereon a band of beads, said beads extendingfrom the top of the band around and underneath the same.

Referring to the drawings, Figure l is a side View of mydevice. Fig. 2is an end view taken 011 the line a: 00 of Fig. 1. Fig. 3 is alongitudinal sectional view of the same, showing in dotted lines the topof the lamp-chimney as inserted in the machine. Fig. 4 is an end Viewtaken on the line a: 00 of Fig. 1, showing the mold portion plaininstead of figured, as shown in Fig. 2. Fig. 5 is a view in perspectiveof one of the jaws detached from the machine.

A indicates the fiai'ingtool, which is rotated from any suitable sourceof power, said fiaring-tool being mounted and adapted to be revolved inthe sleeve or head B. The flaringtool is composed of a cone-shapedcasting in cross-section, with four or more ribs projecting from thecone, and is of the ordinary construction.

On the head or sleeve B is mounted a series of jaws C, said jaws beingpivoted to the head or sleeve B at a. The jaws C are provided withextensions D, which project backward, and are connected to the sleeve E,adapted to work back and forth on the head or sleeve B by means of thelinks F, so that when the sleeve E is drawn back the jaws C will beexpanded to allow the article to be withdrawn from the device. Theforward ends of the jaws O are provided with inwardly- Serial No.343,309. (No model.)

projecting flanges b, which fit over the inner portion of the head B,the inner edges of the flanges Z) being provided with notches orserrations which give to the upper end of the article a series of beadswhich extend from the top around to the bottom of the head.

The jaws O are held in a closed position by the coiled spring G, whichis located lnside of the shank of the sleeve B, so that the aws can onlybe open ed by drawing back the sleeve E. I

The operation of my device is as follows: The tool being in position ina suitable frame, and the flaring-tool being revolved by its shaft H inany suitable manner, the chimney-blank is heated and pressed over theflaring-tool until the upper end of the chimney has been flared andforced out against the corrugated inner surfaces of the jaws O, whichforms a beaded band around the top of the chimney. After the beaded bandhas been formed the sleeve E is drawn back, which opens the aws C andallows the operator to withdraw the article from the device.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is-

1. In a device for forming an ornamental design on the tops oflamp-chimneys or other articles, a fiaringtool, a fixed head having aportion of the ornamental design formed therein, with the series ofnormally-closed jaws having the other portion of the ornamental designformed therein, and mechanism for opening said jaws to release thearticle, substantially as described.

2. In a device for forming an ornamental design on the tops oflamp-chimneys or other articles, a fixed head, and a series ofnormallyclosed movable jaws having each aportlon of the ornamentaldesign formed therein and forming when in operating position thecomplete solid design, and a slide connected to the movable jaws to openthe same, substantially as set forth.

3. In a device for forming an ornamental design on the tops oflamp-chimneys or other articles, a fixed head, and a series ofnormallyclosed movable jaws with their inner faces to abut against thehead and an annular groove formed between their abutting faces, and

mechanism for opening the jaws, substantially as described, forpermitting the removal of the article afterbeing pressed and formed, 5as set forth.

4. In a device for forming an ornamental design on the tops of chimneysand other articles, a fixed head having a portion of the ornamentaldesign formed therein, With a se- 10 ries of normally-spring-closed jawshaving the other portion of the design formed therein, a

collar mounted on a sleeve of the fixed head, and devices for connectingthe sleeve and jaws to overcome the tension of the spring and open thejaws, substantially as set forth. 15
